RETeval
The RETeval device is a powerful aid in the diagnosis and management of retina and optic nerve diseases such as diabetic retinopathy, glaucoma, and inherited retinal dystrophies.
electroretinography (ERG)

The RETeval helps doctors
1. DETECT
Detect various retina and optic nerve diseases earlier
2. PREDICT
Predict the progression of the disease
3. FOLLOW
Then follow up on the course of disease
4. MONITOR
Monitor treatment success

How it works:
1. The RETeval device starts flashing light into the patient’s eye.
2. The retina responds to the flashes by generating small electrical signals that travel through the facial structure to the Sensor Strip.
3. The Sensor Strip detects the electrical signals and compares the results to the age-adjusted reference database.
